I can start, and then I'll turn it over to the general.
Thank you for your question.
As you pointed out and as was mentioned earlier, we are really seeing this strengthening of co-operation, especially between China, Russia, Iran and North Korea. It is intensifying, but at the same time, these four countries still have their own agendas. So it's not an alliance as such, but there's a lot more coordination and co-operation among them. Separately, they have hybrid campaigns, sabotage and espionage programs, and attempts to influence the west and to undermine the status quo everywhere against our allies.
In terms of military co-operation, as we've seen, North Korea is contributing significantly to the conflict in Ukraine, but so is Iran, with Shahed drones and so on. There's increased co-operation.
I'll turn it over to General Ritchie.
